LOOlVI-SHUTTLE.

SPECIFICATION forming part of Letters Patent. No. 383,774, dated May 29,1888.

Application filed August 19, 1887. Serial No. 247,331.

To aZZ whom it mdy concern:

Be it known that I, JAMES C. SnRcnsoN, a citizen of the United States,residing in the city and county ofPhiladelphia, State of Pcnnsylvania,have invented a new and useful Improvement in Loom-Shuttles, whichimprovement is fully set forth in the following spcci' fication andaccompanying drawings.

My invention consists of a loom-shuttlehaving a catch for holding abobbin, the same being released by throwing up the spindle. The catch ispeculiarly constructed, whereby a pivot-pin therefor is dispensed with,and provision is made for preventing the catch when thrown up frombreaking out the shut tle, the several features being hereinafter fullyset forth and definitely claimed.

In the drawings, Figure 1 represents a top or plan view of a portion ofa loom-shuttle embodying my invention. Fig. 2 represents a longitudinalsection thereof. Fig. 3 represents a longitudinal section showing theparts in differentpositions from those shown in Fig.2.

Similar letters of reference indicate corresponding parts in the severalfigures.

Referring to the drawings, A represents the body of a loomshuttle,which, in general respects, is of usual construction.

B represents the spindle for holding the bobbin, the same being securedto a head, 0, which is pivoted to the body, whereby the spindle may bethrown out and in, as is well known in loom shuttles. In the upper partof the head 0 is an opening, D, which is eccentric with the axis of thehead and receives the pivot E of a catch, F, the latter projecting overthe head and having a flange or tongue, G, which is adapted to enter agroove in the bobbin for securing the latter on the spindle. Bearingagainst the under side of the rear or heel end of the catch F is aspring, H, which is seated on the head 0, and serves to hold the tongueend of the catch in engaging contact with the bobbin.

J represents a knuckle,which is freely fitted within the body A,contiguous to the head 0, and consists of a partly-cylindrical pieceforming ajournal, a, an outwardly-projecting lip, b, and alongitudinally-extending stem, 0. In the back of the head 0 is acircular recess, d, which receives the journal a of the knuckle,

(No model.)

said journal being pressed against the headG by means of a spring, K,which bears against the knuckle and a proper part of the body, so thatthe pressure of the spring is exerted against the head 0, for holdingthe spindle B in position. The lip b of the knuckle extends at an angleto the heel of the catch F, and is so disposed that when the spindle isthrown out said heel engages with the lip and motion is imparted to thecatch, so that the front end or tongue, G, thereof is raised clear ofthe bobbin.

When the bobbin is to be removed, the spindle is thrown out, as usual,and the heel of the catch then reaches the lip of the knuckle andimpacts against the same as a deflector. The knuckle slightly yields, soas to prevent binding of the parts, and the catch is forced toward thehead 0, whereby the opposite tongue end is raised and the tongue emergesfrom the groove in the bobbin. As the bobbin is now uncontrolled by thecatch, it may readily be withdrawn from the spindle, as usual.

It will be seen that owing to the knuckle the catch is thrown out, andsaid catch is prevented from bearing against the wall of the slot in thebody in which it plays and breaking out said wall, the body thus beingpreserved intact.

hen the bobbin is restored to the spindle or a fresh bobbin appliedthereto, the spindle is returned into the body of the shuttle, and asthe catch is released of the pressing action of the knuckle or deflectorJ it returns to its normal position, the tongue G then entering thegroove in the bobbin, so that the catch engages with the bobbin, and thebobbin is firmly held on the spindle, the latter retaining its positionin the body owing to the action of the spring K.

The pivot E of the catch Fis integral therewith, and is formed bybending the metal of the same in partly-cylindrical form, leaving acontracted portion or neck, (1, at the place of meeting of the catch andpivot. The outer end of the opening D in the head 0 is also contracted,as at c, and receives the neck d of the catch.

The pivot is inserted in the opening D at the side of the latter, andowing to the contracted portion 0 of said opening the pivot is preventedfrom being displaced, said pivot turning freely on the wall of theopening as its bearings, and a separate or loose pivot-pin beingobviated.

The lower portion of the head 0 is provided with a shoulder orprojection, 0, adapted to be brought in contact with the body of theshuttle when the spindle is thrown in, so as to limit the movementthereof.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A shuttle having a spindle with a springactuated catch pivoted to thehead thereof, and provided with a spring-pressed knuckle having aprojecting lip adapted to bear against the spring-pressed arm of saidcatch when said spindle is elevated, substantially as and for thepurpose set forth.

2. A shuttle having a spindle with a head pivoted to the body of thesaid shuttle, a catch pivoted in an opening in said head and hav-' ingthe spring H, adapted to keep said catch in contact with a bobbin onsaid spindle, and the knuckle J, pivoted to said head and provided withthe projecting lip I), said parts being combined substantially as andfor the purpose set forth.

3. A shuttle having a spindle with its head pivoted to the body of theshuttle, a springactuated catch pivoted to the head, and aspring-pressed knuckle having a lip adapted to bear on thespring-pressed arm of the catch when said spindle is elevated, said headof the spindle having a projection or shoulder on its lower side adaptedto bear against the body of the shuttle, said parts being combined substantially as and for the purpose set forth.

4. A shuttle having the spindle B,with head 0 and spring-actuated catchF, said head being provided with the recess D, open at its ends andhaving therein the pivot E of said catch, the latter being secured tosaid head, and the spring-pressed knuckle J, having its journal a in theopening (I of said head, and the projectinglip b, adapted to bearagainst the heel of said catch F when said spindle is elevated, saidparts being combined substantially as and for the purpose set forth.
